* llint/LLIntCLoop.h:
    CLoop::execute()'s bootstrapOpcodeId does not need a default
    value. There is no case when this function is called without
    that parameter being specified.
* llint/LowLevelInterpreter.asm:
    Moved the dispatchAfterCall() call to where it is needed.
    For the C_LOOP back-end, it generates unreachable code.
* llint/LowLevelInterpreter.cpp:
    #include <wtf/Assertions.h> because LLIntAssembly.h needs it.
(JSC):
    Fixed bug in SIGN_BIT32() macro.
    Placate a MSVC warning for t0, and t1 being uninitialized.
(JSC::CLoop::execute):
    The bootstrapOpcodeId arg should always be specified.
    MSVC doesn't like UNUSED_PARAM() for labels. Switch to using
        the new UNUSED_LABEL() macro.
* offlineasm/cloop.rb:
* offlineasm/generate_offset_extractor.rb:
    Resolved a compiler warning found via MSVC.

Source/WTF: Fixed ASSERT() and ASSERT_AT() macros so that they can be used in
comma expressions. Also, added UNUSED_LABEL().
